Your welcome. But im no expert. Just have a headstart on knowledge since i dove into folding at the pre-annoucement about a week ago. Personally i would say, divide in 3 teams of 8 rigs.... but its just personal tought.... Since i just have 2 machines. 20 Rigs is a whole other setup ....  congratz I had the same question for my 2 rigs. Got answered in a timely manner here : https://foldingforum.org/viewtopic.php?f=61&t=26289#p263876 Foldingforum is the place to be for any and all in dept folding related questions...

Also stated this in one of my previous posts here. So again for anyone reading this. We are welcome guests at foldingforum but guests nonetheless. They are a serious bunch of people who are just in it for the science and the cures and already a bit sceptical on crypto/folding marriage. (Also folding has been around longer then bitcoin... fyi) They do love to help out and answer any questions and generally do so very fast. So lets keep it like that and be polite and friendly when visiting their world.
